LEAD MCMP/MJPEG Codec (2.0)

The LEAD MCMP/MJPEG Codec is a DirectShow® and Microsoft Video For Windows® (VFW) filter for compressing video data using the LEAD CMP and JPEG compression algorithms. The compressed video data can be stored inside AVI files, with or without the audio data. MJPEG, which is also known as Motion JPEG, is a motion video adaptation of the JPEG standard for still photos. MJPEG treats a video stream as a series of still photos, compressing each frame individually, and uses no interframe compression.

MCMP, or Motion CMP, is a motion video adaptation of LEAD's proprietary CMP compression code. MCMP delivers smaller file sizes and can maintain better image quality than MJPEG, with the same or better image quality.

High-speed compression (intraframe only), quick random access to every frame when searching, and the ability to generate a lossless stream enable this codec to be used for wide range of applications such as real time video capturing, video conferencing, remote monitoring and medical imaging.
